Flow of anisometric particles in a quasi-2D hopper
Balazs Szabo, Zsolt Kovacs, Sandra Wegner +4
The stationary flow field in a quasi-two-dimensional hopper is investigated experimentally. The behavior of materials consisting of beads and elongated particles with different asp…
Free Cooling of a Granular Gas in Three Dimensions
Kirsten Harth, Torsten Trittel, Sandra Wegner +1
Granular gases as dilute ensembles of particles in random motion are not only at the basis of elementary structure-forming processes in the universe and involved in many industrial…
Packing, alignment and flow of shape-anisotropic grains in a 3D silo experiment
Tamás Börzsönyi, Ellák Somfai, Balázs Szabó +4
Granular material flowing through bottlenecks like the openings of silos tend to clog and to inhibit further flow. We study this phenomenon in a three-dimensional hopper for spheri…
Heaping, Secondary Flows and Broken Symmetry in Flows of Elongated Granular Particles
Geert Wortel, Tamás Börzsönyi, Ellák Somfai +4
In this paper we report experiments where we shear granular rods in split-bottom geometries, and find that a significant heap of height of least 40% of the filling height can form…
Evolution of shear zones in granular materials
Balazs Szabo, Janos Torok, Ellak Somfai +6
The evolution of wide shear zones (or shear bands) was investigated experimentally and numerically for quasistatic dry granular flows in split bottom shear cells. We compare the be…
Effects of grain shape on packing and dilatancy of sheared granular materials
Sandra Wegner, Ralf Stannarius, Axel Boese +4
Granular material exposed to shear shows a variety of unique phenomena: Reynolds dilatancy, positional order and orientational order effects may compete in the shear zone. We study…
